Extractions: The Millennium Whole Earth Catalog More Reviews Order Info Wiley has published a corrected printing of Applied Cryptography, 2nd ed. They didn't correct everything, only changes that didn't affect page breaks. Still, I counted over 250 individual corrections. And only a dozen errors remaining. The fifth printing or greater is the corrected version. To find what printing you own, turn to page iv (it's opposite the "Contents in Brief" page). The last line (under "Printed in the United States of America") is a series of numbers, counting down from 10. The lowest number is the printing. You have a fifth printing if your last line looks like: If the lowest number is lower than 5, you have an uncorrected printing.

Extractions: Up to The World Wide Web Virtual Library Cryptography There are two kinds of cryptosystems: symmetric and asymmetric . Symmetric cryptosystems use the same key (the secret key) to encrypt and decrypt a message, and asymmetric cryptosystems use one key (the public key) to encrypt a message and a different key (the private key) to decrypt it. Assymetric cryptosystems are also called public key cryptosystems. Symmetric cryptosystems have a problem: how do you transport the secret key from the sender to the recipient securely and in a tamperproof fashion? If you could send the secret key securely, then, in theory, you wouldn't need the symmetric cryptosystem in the first place because you would simply use that secure channel to send your message. Frequently, trusted couriers are used as a solution to this problem. Another, more efficient and reliable solution is a public key cryptosystem, such as RSA , which is used in the popular security tool PGP sci.crypt and sci.crypt.research

Extractions: Concerns about the lack of security online and potential loss of privacy prevent many computer users from realizing the full potential of the Internet. Encryption systems, which scramble electronic communications and information, allow users to communicate on the Internet with confidence, knowing their security and privacy are protected. But the US government blocks export of strong encryption, limiting its widespread use. HEADLINES House Passes Money Laundering Bill; Senator Drops Call for Crypto Controls - The House of Representatives on Wednesday, Oct. 17 passed an amended version of H.R. 3004 - the Financial Anti-Terrorism Act of 2001. Stripped from the bill was a prohibition of Internet gambling and measures that raised civil liberties concerns such as asset forfeiture and warrantless searches of outgoing international mail. Also this week, Senator Judd Gregg (R-NH) backed off his call for anti-encryption mandates.

Public-Key Cryptography Standards The Public-Key Cryptography Standards are specifications produced by RSA Laboratories in cooperation with secure systems developers worldwide for the purpose of accelerating the deployment of public-key cryptography. First published in 1991 as a result of meetings with a small group of early adopters of public-key technology, the PKCS documents have become widely referenced and implemented. Contributions from the PKCS series have become part of many formal and de facto standards, including ANSI X9 documents, PKIX, SET, S/MIME, and SSL. Further development of PKCS occurs through mailing list discussions and occasional workshops, and suggestions for improvement are welcome.

Extractions: Media Coverage of Recent Proposals Previous News Reports Policy Areas ... Other Materials In the wake of the terrorist attacks in New York City and Washington D.C. on September 11, 2001, there have been renewed calls among some lawmakers for restrictions on the use and availability of strong encryption products. In Congressional floor statements on September and , Senator Judd Gregg (R-NH) called for a global "new regime" in the area of encryption which would grant law enforcement access to private keys. Sen. Gregg has now stated, however, that he does not intend to introduce a bill to give effect to this proposal. Civil liberties and privacy advocates strongly oppose any attempts to require key escrow, key recovery or other means of accessing encryption keys, arguing that they are an unjustified restriction of individuals' fundamental privacy rights, detrimental to security, costly, subject to massive abuse, and ultimately ineffective crime prevention methods. Technology and security experts also oppose any restricitons on encryption, arguing that they would damage comsumer trust in e-commerce transactions.

Extractions: Java TM Cryptography Extension (JCE) The Java TM Cryptography Extension (JCE) is a set of packages that provide a framework and implementations for encryption, key generation and key agreement, and Message Authentication Code (MAC) algorithms. Support for encryption includes symmetric, asymmetric, block, and stream ciphers. The software also supports secure streams and sealed objects. JCE is designed so that other qualified cryptography libraries can be plugged in as service providers, and new algorithms can be added seamlessly. (Qualified providers are signed by a trusted entity.) JCE has been integrated into the Java TM 2 SDK, Standard Edition, v 1.4 The previous release, JCE 1.2.2 , is an optional package to the Java TM 2 SDK, versions 1.2.x and 1.3.x.

Extractions: Counter: Reset on 15/07/02 with over 115,000 hits since Nov '98 The Delphi Cryptography Page The Science of Secrecy. I have been interested in cryptography for about 4-5 years now and part of my contribution to the advancement in this area is the cryptographic component library DCPcrypt . The project stalled about 2 years ago but now is back on track! DCPcrypt v2 for Delphi, C++ Builder and Kylix DCPcrypt is an open source library of cryptographic components (encryption and hash algorithms) for Borland Delphi 4, 5, 6, 7, C++ Builder (3?), 4, 5, 6 and Kylix 1, 2 for Linux. Although the library itself is open source, some of the algorithms within the package require licensing from the respective patent holders. The idea behind DCPcrypt is that it should be possible to "drop in" any algorithm implementation to replace another with minimum or no code changes. To aid in this goal all cryptographic components are descended from one of several base classes, TDCP_cipher for encryption algorithms and TDCP_hash for message digest algorithms. DCPcrypt v2 contains full implementations of the following algorithms: Encryption Algorithms Hash Algorithms Blowfish Cast 128 Cast 256 DES, 3DES

Elliptic Curve Cryptography Elliptic Curve cryptography. On this page What is an Elliptic Curve? Whydo we care? So what's a group? Is Elliptic Curve cryptography Safe? http://world.std.com/~dpj/elliptic.html

Extractions: A list of everything on this site. The study of elliptic curves is an important branch of mathematics. Elliptic curves are simple functions that can be drawn as gently looping lines in the (x,y) plane. Very simple. Basic high school stuff. But wierd and interesting things happen when mathematicians study the points where the curve exactly crosses integer (x,y) coordinates. Although the study of elliptic theory is far beyond what normal people will experience in school, the field has been well studied by mathematicians for many years, and in the latter half of the 20th century it has yielded some very significant results. Elliptic Curve Cryptography is just one application of elliptic curve theory.

Extractions: Author: C. B. Roellgen 20.04.2002 The history of cryptography has shown that unbreakable ciphers had in many cases been cracked shortly after their widespread use had begun. One famous example is the "Enigma" encryption machine used by the Nazis in world war two: British specialists at Bletchley Park had been able to crack the clever permutation code. This resulted in detailed knowledge about most German military operations and in the total loss of the German submarines. Fig. 1 The widespread DES algorithm has long been supposed to be unbreakable. In January 1999 a test performed by RSA Data Security, Inc. (San Mateo, Calif., USA) proved that it takes less than 22.25 hours to crack the 56 bit algorithm by brute-force (by trying all 256 possibilities). That was 365 days after the same company needed 41 days for that task! RSA claim to have a much better cipher, which is obviously true. Today a code length of 128 bit is regarded as safe by experts (1000 bit for RSA). Thus, it took just 25 years for the experts to actually double their requirements in key size (which is effectively 10000000000000000000 times more than what was initially regarded "safe"!!!).
